MultiTherm OG-1®

Purpose 
MultiTherm OG-1® is a hydrocracked base oil combined with the latest proprietary oxidation inhibitor/stabilizer. MultiTherm OG-1® was designed to meet the rising and demanding re of liquid phase open-loop heat transfer fluid system applications.

Oxidation 
The most common form of contamination is oxidation of the heat transfer fluid. Excessive oxidation can create solids and high viscosity compounds that impair system effectiveness. Oxidation and fluid boil-off are major problems when using organic heat transfer fluids in an open-loop systems. Oxidation produces organic acids, which can polymerize and create deposits.

Open Systems
MultiTherm OG-1® is designed for use in li heat transfer fluid systems, which are “open” to the atmosphere or there is a possibility that the heat transfer fluid in the expansion tank will come in contact with air. To reduce the oxidation process in an open-loop system, MultiTherm OG-1® is enhanced with special oxidation inhibitors to prevent this oxidative degradation and deposits.

MultiTherm OG-1® heat transfer fluid is designed for a maximum film temperature of 600°F / 316°C and a maximum system bulk temperature of 550°F / 290°C.
